Description

  The present invention relates to a video processing apparatus and a video processing apparatus control method.

  Currently, three-dimensional (3D) video broadcasting (3D broadcasting) is performed. For example, in the BS11 channel of digital satellite broadcasting, 3D broadcasting is performed by a “side-by-side method” in which one-screen video is divided into left-eye video and right-eye video and transmitted. As main display methods for 3D images, a “polarization method” and an “active shutter method” are known.

  In the case of the polarization method, a 3D broadcast receiving apparatus has a film having polarization characteristics on a display panel, and displays an image for left eye and an image for right eye interlaced. The viewer can recognize the image three-dimensionally by wearing polarized glasses and viewing the left eye image display line with the left eye and the right eye image display line with the right eye.

  In the case of the active shutter system, the 3D broadcast receiving apparatus alternately displays the left-eye video and the right-eye video. The viewer wears glasses having a liquid crystal shutter. The glasses control the liquid crystal shutter so that the left-eye video only enters the left eye and the right-eye video only enters the right eye. Thus, the viewer can recognize the image three-dimensionally.

  Incidentally, a phenomenon called “burn-in” may occur in the display panel. Burn-in is a phenomenon in which the light emitting element is deteriorated by lighting the light emitting element for a long time and the light emitting function does not work normally. In particular, when a still image or a moving image including a still area is displayed for a long time, the image may remain like an afterimage due to burn-in.

  As described above, image sticking occurs due to deterioration of the light emitting element, and can occur in any of a two-dimensional (2D) image and a 3D image. Currently, several techniques for suppressing the occurrence of burn-in are known.

  Patent Document 1 discloses a technique for reducing burn-in by a so-called “pixel shift” method in which the display position is moved by changing the display size of an image when the input image does not change for a certain period of time.

  Patent Document 2 discloses that an input format is detected and interpolation processing is performed in accordance with the display size. Then, by moving the display position of the image horizontally and vertically in a predetermined pixel range by one pixel every predetermined time, it is possible to reduce image burn-in and reduce burn-in. is doing.

  Patent Documents 1 and 2 are intended to apply pixel shifting to 2D video, and do not consider that the video includes a left-eye video and a right-eye video. However, when conventional processing such as pixel shifting is applied to 3D video, the video may be recognized with a stereoscopic effect different from the original stereoscopic effect intended by the 3D video producer for the following reasons. .

  For example, in the case of the polarization method, when the pixel of the left-eye image moves to the position of the pixel of the right-eye image and the pixel of the right-eye image moves to the position of the pixel of the left-eye image, the left and right parallax are reversed. In the case of the active shutter system, if the amount of pixel movement in the left-eye image is different from the amount of pixel movement in the right-eye image, the parallax between the two images changes. In the 3D video, the parallax (binocular parallax) between the left-eye video and the right-eye video is provided, so that a human can recognize the video three-dimensionally. However, it is assumed that the parallax considered at the time of video design changes due to the burn-in control, so that the stereoscopic video is blurred or invisible in some cases. That is, the conventional burn-in reduction technology has not considered the problem of burn-in in 3D video.

  The present invention has been made in view of such a situation, and an object thereof is to provide a burn-in reduction technique for 3D video.

  In order to solve the above problems, the present invention provides a video processing apparatus that outputs video to a display device having a display area including a first display unit that displays a left-eye image and a second display unit that displays a right-eye image. The arrangement pattern of the left-eye image and the right-eye image is displayed in the display area from the three-dimensional video configured as a set of a left-eye image and a right-eye image corresponding to the same scene. Generating means for generating a display three-dimensional image processed so as to match the arrangement pattern of the display unit and the second display part, video processing means for cutting out a part of the display three-dimensional image, and the video processing means Output means for outputting the partial image cut out to the display device, and the video processing means, when changing the cut-out position of the partial image, the left-eye image and the partial image after the change of the cut-out position. Video processing, wherein the partial image is cut out from the display three-dimensional image so that the arrangement pattern of the right-eye image matches the arrangement pattern of the first display unit and the second display unit in the display region Providing equipment.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. The technical scope of the present invention is determined by the scope of the claims, and is not limited by the following individual embodiments. In addition, all combinations of features described in the embodiments are not necessarily essential to the present invention.

  In each of the following embodiments, the case where the video processing apparatus of the present invention is applied to a broadcast receiving apparatus will be described. However, the application example is not limited thereto, and the video processing apparatus of the present invention is applied to a video reproduction apparatus such as a DVD player. It is also possible to apply.

  In the first embodiment, a case where a polarization method is used as a display method of a three-dimensional image (3D image) will be described. Accordingly, the 3D video is configured as a set of a left-eye image and a right-eye image corresponding to the same scene. FIG. 1 is a conceptual view of a display panel 101 that displays a 3D image by a polarization method as viewed from the side. FIG. 2 is a conceptual diagram of the display panel 101 as viewed from the front.

  The display panel 101 receives and displays the video output from the broadcast receiving device. The display panel 101 is configured by an arbitrary method such as a liquid crystal method, a plasma method, or a surface-conduction electron-emitter display (SED) method.

  A polarizing filter 102 is affixed on the display panel 101 (display device). As shown in FIG. 2, in the polarizing filter 102, odd-numbered lines (L1, L2,...) Serve as left-eye display lines (first display section), and even-numbered lines (R1, R2,. It is comprised so that it may become a display line (2nd display part). Therefore, the left-eye image and the right-eye image are displayed by light having different vibration directions. The viewer (user) views the video by wearing dedicated polarizing glasses 104 using polarization filters in different directions with the left and right eyes (FIG. 1 shows only one eye 103), thereby viewing the video as a 3D video. Recognize as

  FIG. 3 is a block diagram illustrating a schematic configuration of the broadcast receiving apparatus 300 according to the first embodiment. In FIG. 3, the CPU 301 controls the entire broadcast receiving apparatus 300 according to a program stored in the ROM 302.

  A RAM 303 is a volatile memory, used as a work memory for the CPU 301, and also used as a temporary storage area for various data. In particular, the first memory area 304 stores a 2D pixel shift table, and the second memory area 305 stores a 3D pixel shift table.

  FIG. 4 is a conceptual diagram of a 2D pixel shifting table and a 3D pixel shifting table. Each table displays a video display start position (for example, [1] corresponding to the number of occurrences (N = 1, 2, 3,...) Of the burn-in reduction trigger signal (described later in conjunction with the description of the display position control unit 311). , 1]). In the example of FIG. 4, the 2D pixel shift table is configured to change the display start position pixel by pixel in the x direction or the y direction each time a trigger signal is generated (change process). The 3D pixel shift table changes the display start position by one pixel in the x direction (horizontal direction) and 2n pixels in the y direction (vertical direction) each time a trigger signal is generated (n is a natural number). Configured as follows. That is, when pixel shifting is performed on a three-dimensional image including a pair of left-eye video and right-eye video alternately corresponding to the same scene in each horizontal line, the display start position is in the vertical direction. Move 2n (n is a natural number) lines. In addition, it is possible to suppress the disturbance of the video by moving according to the law according to the video format (whether it is 2D video or 3D video).

  Instead of the table, for example, a calculation formula for determining the display start position may be used. FIG. 4 only shows the number of trigger signals generated up to the fourth (N = 4). Actually, the pixel shift table can also hold the display start positions corresponding to the trigger signals after the fifth. is there. However, when four trigger signals are used as one cycle, it is sufficient for the pixel shift table to hold display start positions corresponding to four trigger signals.

  The tuner unit 306 demodulates a broadcast wave received from an antenna (not shown) and outputs video and audio baseband data. The demultiplexer unit 307 performs frame decomposition on the data received from the tuner unit 306 and separates video data, audio data, and program information data.

  The video data and audio data separated by the demultiplexer unit 307 are input to the decoder unit 308. The decoder unit 308 decodes the MPEG2-encoded video data and inputs it to the 3D video generation unit 310. Also, the MPEG2-AAC encoded audio data is decoded and converted into a linear PCM format and input to the audio processing unit 315.

  The program information data separated by the demultiplexer unit 307 is input to the video determination unit 309. The program information data is transmitted in a data structure defined by the standard of the Japan Radio Industry Association (ARIB), such as “program arrangement information used for digital broadcasting”. The main configuration data includes SDT that transmits information related to the organization channel, and EIT that transmits information related to the program, such as the program name, broadcast time, and component type to be transmitted. SDT is an abbreviation of Service Description Table, and EIT is an abbreviation of (Event Information Table.

  In this embodiment, a 3D video format is additionally defined in the currently standardized video component type (component_type). The video determination unit 309 determines whether the format of the video data being decoded by the decoder unit 308 is 2D video (2D video) or 3D video based on the component type inserted into the EIT, The determination result is notified to the 3D video generation unit 310.

  When the video format notified from the video determination unit 309 is a 3D video, the 3D video generation unit 310 performs 3D processing of the video input from the decoder unit 308. Specifically, the 3D video generation unit 310 configures the frames constituting the video input from the decoder unit 308 so that the left-eye image is displayed on the odd-numbered lines in FIG. 2 and the right-eye image is displayed on the even-numbered lines. The image is processed and input to the resolution conversion unit 313. When the video format is 2D video, the 3D video generation unit 310 inputs the video input from the decoder unit 308 to the resolution conversion unit 313 without processing. As an embodiment of the present invention, a video is defined as one in which a plurality of images are sequentially displayed in the time direction. Therefore, the resolution conversion and the display position cut-out process are not performed on the video, but are performed on each image constituting the video.

  The display position control unit 311 determines the display area (predetermined area) of the image whose resolution is converted by the resolution conversion unit 313 (described later) based on the determination result of the video determination unit 309. Then, the display position control unit 311 inputs an image (partial image) cut out from the determined display area to the video processing unit 314. Specifically, in the case of 2D video, the 2D pixel shift table stored in the first memory area 304 is used, and in the case of 3D video, the 3D pixel shift stored in the second memory area 305 is used. The display start position of the video is determined using the table. For example, when the image size of the video is 1920 × 1080, an image having a size of 1900 × 1070 is cut out from the display start position and input to the video processing unit 314. Therefore, “pixel shift” may be interpreted as a process of moving the cutout region of the image output to the display panel 101 according to the display start position. Of course, the process of simply moving the display position without cutting out the image corresponds to the pixel shifting process.

  The frame number measurement unit 312 counts the number of frames of video output to the display panel, and transmits a burn-in reduction trigger signal to the display position control unit 311 when the count reaches a predetermined number. When receiving the burn-in reduction trigger signal, the display position control unit 311 updates the display start position based on the pixel shift table corresponding to the video format.

  The condition for generating the burn-in reduction trigger signal is not limited to the number of frames. For example, a trigger signal may be generated when a channel change is detected based on the program information data described above, or when a channel is switched based on a user operation using the remote controller 317 or the like.

  The resolution conversion unit 313 performs resolution conversion according to the display panel 101 on the video input from the 3D video generation unit 310. In this way, 2D video or 3D video to be subjected to pixel shift processing is acquired. Therefore, the resolution conversion unit 313 can acquire 2D video or 3D video. The resolution conversion unit 313 sends the video whose resolution has been converted to the display position control unit 311.

  The video processing unit 314 performs γ processing or the like on the image (partial image) input from the display position control unit 311, and then converts the video data to video data suitable for the display panel 101 such as an LVDS signal and outputs the video data. .

  The audio processing unit 315 performs D / A conversion processing or the like on the audio data and outputs the audio data to the speaker 316. The remote controller 317 transmits a control signal as an infrared signal in response to a user operation. The CPU 301 generates and outputs various commands and control signals for controlling the broadcast receiving device 300 from the infrared signal received by the infrared light receiving unit 318.

  In this example, for the sake of explanation, the left-eye image is displayed on the odd lines of the display panel 101, and the right-eye image is displayed on the even lines of the display panel 101 (see FIG. 2). However, the arrangement of the left-eye image and the right-eye image is not limited to this. For example, the left-eye image pixels and the right-eye image pixels may be arranged in a checkered pattern. Whatever the arrangement of the left-eye image and the right-eye image, the pixel of the left-eye image moves to the position of the pixel of another left-eye image, and the pixel of the right-eye image is the pixel of another right-eye image. If the pixel shift table is created so as to move to the position, the desired effect can be achieved. In other words, the display position control unit 311 displays the display portion of the 3D image for display that constitutes the 3D image so that the arrangement pattern of the left-eye image and the right-eye image of the 3D image matches the arrangement pattern of the polarization filter 102, That is, an area cut out as a partial image is selected. Thereby, display is performed as a 3D video. In the burn-in reduction process, the cutout position of the partial image is moved so that the arrangement pattern of the left-eye image and the right-eye image does not change. That is, after the cutout position is moved (after change), the cutout position is moved so as to match the arrangement pattern of the polarizing filter 102. Note that the movement of the cutout position is not necessarily required in the present invention. That is, it is possible to change the display position of the display image itself. In this process, an area in which no image is displayed on the display screen, that is, a blanking area is generated. However, since it is possible to eliminate the display image being always displayed at the same position, burn-in can be reduced.

  FIG. 5 is a flowchart showing burn-in reduction processing by the broadcast receiving apparatus 300. When the above-mentioned burn-in reduction trigger signal is generated, the processing of this flowchart is started. In step S501, the video determination unit 309 extracts a component type from the component descriptor of the EIT. In step S502, the video determination unit 309 determines whether the video format of the video data being decoded by the decoder unit 308 is 2D video or 3D video. In the case of 2D video, the process proceeds to S503, and in the case of 3D video, the process proceeds to S505.

  In step S <b> 503, the display position control unit 311 reads the 2D pixel shift table from the RAM 303. In step S504, the display position control unit 311 sets the corresponding display start position for 2D based on the number of times the trigger signal is generated (that is, the number of trigger signals that started the current process in the flowchart). Obtained from the pixel shift table.

  On the other hand, in step S <b> 505, the display position control unit 311 reads the 3D pixel shift table from the RAM 303. In step S506, the display position control unit 311 acquires the corresponding display start position from the 3D pixel shift table based on the number of times the trigger signal is generated.

  In step S507, the display position control unit 311 cuts out an image based on the display start position acquired in step S504 or S506, and inputs the image to the video processing unit 314.

  The format of the burn-in reduction trigger signal may be defined so that the display position control unit 311 can recognize the cause of the occurrence of the burn-in reduction trigger signal. In this case, once the processing for determining the type of video format (S501 and S502) is performed once, this processing is performed unless the cause of the occurrence is a video format change (for example, channel switching). Can be omitted.

  As described above, according to the present embodiment, the broadcast receiving apparatus 300 moves the area of the video output to the display panel 101 in order to reduce the burn-in of the display panel 101. When the video is a 3D video, the broadcast receiving apparatus 300 displays the pixel of the left-eye image at the position of the pixel of the left-eye image of the display panel 101 and the pixel of the right-eye image of the pixel of the right-eye image of the display panel 101. The area is moved so that it is displayed at the position. In this way, a burn-in reduction technique for 3D video is provided.

  In the second embodiment, a case where an active shutter system is used as a 3D video display system will be described. FIG. 6 is a conceptual diagram of 3D video display by the active shutter method. As shown in FIG. 6, left-eye images (L_t1, L_t3,...) And right-eye images (R_t2, R_t4,...) Are alternately displayed in time series, and the stereoscopic effect is given by the parallax between both images. can get.

  FIG. 7 is a block diagram illustrating a schematic configuration of the broadcast receiving apparatus 700 according to the second embodiment. In FIG. 7, the same components as those of the broadcast receiving apparatus 300 (FIG. 3) are denoted by the same reference numerals, and description thereof is omitted.

  The decoder unit 701 includes a first decoder 702 that decodes a left-eye image and a second decoder 703 that decodes a right-eye image, and decodes MPEG2-encoded video data input from the demultiplexer unit 307. To the decoder switching unit 704. Also, the MPEG2-AAC encoded audio data is decoded and converted into a linear PCM format and input to the audio processing unit 315.

  The decoder switching unit 704 alternately inputs the left-eye image and the right-eye image input from the decoder unit 701 to the resolution conversion unit 313. Thus, by using two decoders together, it becomes possible to display video at a higher frame rate.

  The display position control unit 705 determines the display area of the image whose resolution is converted by the resolution conversion unit 313 based on whether the image is for the left eye or the right eye and the determination result of the video determination unit 309, and the determined display The partial image cut out from the area is input to the video processing unit 314. When determining the display area, the display position control unit 705 matches the display start positions of the pair of left-eye images and right-eye images.

  When the video data is 3D video, the glasses control unit 706 enters the left-eye image only in the left eye and the right-eye image only in the right eye in synchronization with the timing of alternately displaying the left-eye image and the right-eye image. Thus, the liquid crystal shutter of the glasses 707 is controlled.

  Unlike the display panel 101 of the first embodiment, the display panel 708 does not have a polarizing film. The first memory area 709 holds a 2D pixel shift table, and the second memory area 710 holds a 3D pixel shift table. However, unlike the first embodiment, since the left-eye image and the right-eye image are not mixed in one frame, the design of the 3D pixel shift table is not restricted by the arrangement of the polarizing film.

  FIG. 8 is a flowchart showing burn-in reduction processing by the broadcast receiving apparatus 700. In FIG. 8, steps in which processing similar to that in Embodiment 1 (FIG. 5) is performed are denoted by the same reference numerals, and description thereof is omitted. When the burn-in reduction trigger signal is generated, the processing of this flowchart starts.

  In the second embodiment, the pixel shift table is generated for a single trigger signal such as N = {1, 2,...} = {[1, 1], [7, 1],. Assume that the display start position is configured to move two or more pixels. In this case, if the display start position is moved at a time when moving from one frame to the next frame, the movement may be perceived by human eyes and perceived as disturbance of the image. Therefore, in this embodiment, the display position control unit 705 moves from the display start position before the trigger signal is generated (for example, [1, 1]) toward the display start position after the generation (for example, [7, 1]). It is assumed that the display start position is gradually moved over several frames.

  In step S <b> 801, the display position control unit 705 acquires a display start position corresponding to the number of trigger signal occurrences from the 2D pixel shift table and sets it as a target movement position. In step S802, the display position control unit 705 moves the display start position by a predetermined unit (for example, one pixel). For example, when the display start position before the movement is [1, 1] and the target movement position is [7, 1], the display start position after the movement is [2, 1].

  In step S803, the display position control unit 705 cuts out an image based on the display start position moved in step S802, and inputs the image to the video processing unit 314. In step S804, the display position control unit 705 determines whether the display start position has reached the target movement position. If not reached, the process returns to S802, and if reached, the process is terminated.

  On the other hand, in step S805, the display position control unit 705 acquires the display start position corresponding to the number of occurrences of the trigger signal from the 3D pixel shift table and sets it as the target movement position. In step S806, the display position control unit 705 determines whether the processing target video is a left-eye image. If it is a left-eye image, the process proceeds to S807, and if not, the process proceeds to S808.

  In step S807, the display position control unit 705 moves the display start position by a predetermined unit (for example, one pixel). For example, when the display start position before movement is [1, 1] and the target movement position is [5, 1], the display start position after movement is [2, 1].

  In step S808, the display position control unit 705 cuts out an image based on the display start position moved in step S807, and inputs the image to the video processing unit 314. In step S809, the display position control unit 705 determines whether the display start position has reached the target movement position. If not reached, the process returns to S806, and if reached, the process is terminated.

  As can be understood from S806 to S809, since the display start position is not moved when the video to be processed is a right-eye image, a pair of left-eye and right-eye images corresponding to the same scene is displayed. The start position matches. Therefore, the parallax is prevented from changing between the left-eye image and the right-eye image corresponding to the same scene.

  FIG. 9 is a conceptual diagram showing how the display start position moves according to the flowchart of FIG. As shown in FIG. 9, in the case of 3D video, the display start positions of a pair of left-eye images and right-eye images (for example, L_t1 and R_t2) corresponding to the same scene match. In other words, the display start position is not moved at a timing other than the timing at which one set of left-eye images and right-eye images corresponding to the same scene is switched to the next set of left-eye images and right-eye images. .

  If the movement amount is set to 0 as the coordinate value of the 3D pixel shifting table, it means that the pixel shifting process is stopped. When the motion vector between frames is large in the decoder unit 701, it is considered that the motion of the object in the video is intense. In this case, when pixel shifting is applied, the image is noticeably disturbed and the 3D effect is reduced. Therefore, the decoder unit 701 divides the frame into a plurality of regions, refers to the motion vector for each small region, and notifies the display position control unit 705 of the average motion amount of the object in the frame.

  Even if the burn-in reduction trigger signal is generated, the display position control unit 705 sets the movement amount to 0 as the coordinate value of the 3D pixel shift table if the received average motion amount exceeds a predetermined threshold value. Replace and process. As a result, reduction of the 3D effect can be avoided. In this case, since the movement of the object itself in the video is large, the image sticking that causes an afterimage is unlikely to occur.

  As described above, according to the present embodiment, the broadcast receiving apparatus 700 moves the area of the video output to the display panel 708 in order to reduce the burn-in of the display panel 708. When the video is a 3D video, the broadcast receiving apparatus 700 moves the region so that the display start positions of the left-eye image and the right-eye image corresponding to the same scene match. Therefore, the parallax is prevented from changing between the left-eye image and the right-eye image corresponding to the same scene. In this way, a burn-in reduction technique for 3D video is provided.
